Cabbirka caadiga ah ee fiilada daawaha nikkel:

Waxaan ku bixinnaa alaab qaab silig ah, silig fidsan, iyo xarig. Waxaan sidoo kale samayn karnaa agab loo habeeyey iyadoo loo eegayo codsiyada isticmaaleyaasha.

Silig dhalaalaya oo cad - 0.025mm ~ 3mm

Silig lagu shubo: 1.8mm ~ 10mm

Silig Oxidized: 0.6mm ~ 10mm

Silig fidsan: dhumucdiisuna waa 0.05mm ~ 1.0mm, ballackeeduna waa 0.5mm ~ 5.0mm

Geedi socodka:

Silig: Diyaarinta walxaha → dhalaalid → dib-u-dhalaalid → foori → duubid kulul → daawaynta kulaylka → daawaynta dusha sare → sawir (rogid) → dhammaystir daawaynta kulaylka → kormeer → xirmo → bakhaar

Astaamaha alaabta ee fiilada nichrome:

1) Xoog aad u fiican oo ka hortagga oksaydhka iyo farsamada heerkulka sare;

2) Iska caabin sare iyo isku-darka heerkulka hooseeya ee iska caabinta;

3) Dib-u-habeyn heer sare ah iyo waxqabad sameynta;

4) Waxqabadka alxanka oo aad u fiican
